Ingredients
- 1 cup pumpkin puree
Pumpkin puree is the star of this recipe, providing moisture and a rich, slightly sweet flavor. It's also packed with nutrients like beta-carotene, making your dessert a deliciously wholesome option. - 1/2 cup granulated sugar
Granulated sugar sweetens the cake and helps achieve a lovely caramelization on the edges. This sweetness balances the spices and the natural earthiness of the pumpkin. - 1/4 cup brown sugar
Brown sugar brings a hint of molasses flavor and contributes to a moist texture. It caramelizes beautifully, enhancing the cake's complexity and deep autumn flavor. - 1/2 cup vegetable oil
Vegetable oil adds moisture to the cake without altering its flavor. It keeps the crumb tender and helps in achieving a soft cake that melts in your mouth. - 2 large eggs
Eggs function as a binding agent that holds the cake together while contributing to its structure. They also add richness and support the cake’s rise. - 1 1/2 cups all-purpose flour
All-purpose flour provides the necessary structure for the cake. It absorbs moisture and helps create a fluffy texture when combined with wet ingredients. - 1 tsp baking powder
Baking powder is crucial for leavening, giving the cake a light and airy texture. It reacts with the wet ingredients, creating bubbles that help the cake rise. - 1/2 tsp baking soda
Baking soda works alongside the baking powder to further enhance the cake’s lift. It also helps neutralize the acidity from the pumpkin, resulting in a balanced flavor. - 1 tsp ground cinnamon
Ground cinnamon infuses the cake with warm, aromatic flavor that defines pumpkin spice. Its familiarity evokes cozy autumn memories and enhances the overall taste. - 1/2 tsp ground nutmeg
Nutmeg adds depth and a slightly sweet-sour flavor that complements pumpkin beautifully. A little goes a long way in creating a well-rounded spiced flavor profile. - 1/4 tsp ground ginger
This spice offers a zesty kick that livens up the cake, balancing the sweetness of the pumpkin and sugars. Ginger is a key player in traditional pumpkin spice blends. - 1/4 tsp salt
Salt enhances the flavors in the cake, helping to balance the sweetness and spices. It acts as a flavor amplifier, ensuring each bite is well-rounded. - 1/2 cup rolled oats
Rolled oats add a hearty texture to the crumble topping while providing additional fiber. They absorb moisture and create a satisfying crunch that contrasts with the soft cake. - 1/2 cup brown sugar (for crumble)
This brown sugar adds sweetness and moisture to the crumble topping, giving it a rich flavor. The moisture helps the crumble clump together for a satisfying crunch. - 1/4 cup all-purpose flour (for crumble)
Flour in the crumble binds the ingredients together, ensuring it holds shape when baked. It contributes to the crispy texture of the topping, enhancing the overall experience. - 1/4 cup cold butter, cubed
Cold butter is essential for creating a flaky, crumbly texture in the topping. It should be kept chilled, as warming it can lead to a less desirable consistency.
Directions & Preparation
Step 1: Preheat your oven to 350°F (175°C) and grease a baking dish.
Preheating the oven ensures that the cake bakes evenly right from the start. Greasing the baking dish helps prevent the cake from sticking, allowing for easy removal after baking, maintaining its beautiful shape.
Step 2: In a large mixing bowl, combine the pumpkin puree, granulated sugar, brown sugar, vegetable oil, and eggs. Mix until smooth.
Mixing these wet ingredients together first creates a uniform base for the cake. The sugars dissolve into the pumpkin and oil, ensuring a consistent sweetness and moisture throughout the batter.
Step 3: In a separate bowl, whisk together the flour, baking powder, baking soda, spices, and salt.
Whisking the dry ingredients separately allows for even distribution of the leavening agents and spices. This step is crucial; incorporating them thoroughly will prevent clumps that can lead to uneven baking.
Step 4: Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Mixing until just combined helps avoid overworking the batter. Overmixing can develop gluten in the flour, resulting in a tougher cake instead of the desired tender texture.
Step 5: Prepare the crumble topping by combining oats, brown sugar, flour, and cubed cold butter in a bowl.
Combining the dry ingredients first allows the oats and flour to absorb the sweetness. The cold butter, when cut in, creates a crumbly texture that bakes into a delightful crunch on top of the cake.
Step 6: Use your fingers or a fork to blend the butter into the mixture until it resembles coarse crumbs.
This step is pivotal for achieving the right crumble texture. Your fingers will warm the butter slightly while mixing, creating clumps that will bake to a crispy finish. Avoid melting the butter for best results.
Step 7: Pour the pumpkin batter into the greased baking dish and spread evenly.
Spreading the batter evenly ensures even baking. A thicker layer in some areas could lead to uneven cooking, so take your time to level it out before adding the crumble topping.
Step 8: Sprinkle the crumble mixture evenly over the pumpkin batter.
Even distribution of the crumble mixture is important to ensure every bite has that crunchy texture. This topping will caramelize and crisp up during baking, adding a delightful contrast to the moist cake.
Step 9: Bake in the preheated oven for 25–30 minutes, or until a toothpick comes out clean.
Monitoring the baking time is crucial to avoid overbaking. A toothpick inserted into the center of the cake should come out clean or with a few moist crumbs attached. Keep an eye on it to ensure a perfect texture.
Step 10: Allow the cake to cool in the pan for about 10 minutes before slicing and serving.
Cooling the cake slightly in the pan helps it set, making it easier to slice. If served too warm, it may crumble and fall apart. This brief cooling time improves the presentation and overall enjoyment.

Chocolate Drizzle for Extra Indulgence
For those looking to elevate their Pumpkin Spice Crumble Cake even further, consider drizzling melted chocolate over the top before serving. The bittersweet flavor of chocolate complements the spices and pumpkin, creating a rich combination that adds a touch of luxury. Just melt some dark or semi-sweet chocolate with a bit of cream, drizzle it over the cooled cake, and watch it disappear quickly.
Spice Variations to Customize Your Cake
While this recipe calls for classic pumpkin spices, feel free to get creative! Add a pinch of allspice or a dash of cardamom for an additional layer of depth. These spices can enhance the cake's flavor profile, making it distinctly your own. Personalizing your spice blend not only changes the taste but also the aroma, filling your kitchen with warm, inviting scents.
Serve with Whipped Cream for the Perfect Pairing
Nothing complements a slice of Pumpkin Spice Crumble Cake like a dollop of freshly whipped cream. The lightness of the cream enhances the density of the cake, providing a balanced mouthfeel. To elevate this pairing, consider adding a splash of vanilla extract or a sprinkle of cinnamon to the cream before whipping, intensifying its relationship with the spiced cake.
FAQs
What if my batter is too thick?
If your batter seems overly thick, it might be due to adding too much flour. Try adding a small splash of milk or water to thin it out slightly before baking.
Can I use a different type of sugar for the crumble?
Yes, you can use coconut sugar or even maple sugar as a substitute for brown sugar in the crumble. Just be aware that it may alter the flavor slightly, adding a unique twist.
How can I tell if my cake is baked properly?
Insert a toothpick into the center of the cake; it should come out clean or with a few moist crumbs. If it comes out wet, bake for a few more minutes and check again.
What should I do if my crumble topping burns?
If the topping starts darkening too quickly, cover the pan loosely with aluminum foil to allow the cake to finish baking without further browning the crust.
Can I bake this in a different pan?
Yes, this recipe works well in a square or round pan. Just keep an eye on the baking time, as different pans may cook the batter more quickly or slowly.
How can I make this cake spicier?
To increase the spice level, you can add more cinnamon or a dash of cayenne pepper to the batter. Start with a small amount and adjust to taste for the desired kick.
